DUMPING-WAGON.

SPECIFICATION forming part of Letters Patent No. 671,290, dated April 2, 1901.

Application filed December 7, 1900. Serial No. 39,073- (No model.)

To ctZZ whom it may concern:

Be it known that I, ERNST MULLER, a citizen of the United States, and a resident of the ed a new and Improved Dumping-Wagon, of

which the following is a full description.

,clear, and exact Thisinvention relates toadumping-wagonwhich I have constructed with certain novel features tending to improve the manner of framing the bed of the wagon and of mounting the dumping-body thereon.

This specification is a specific description of one form of the invention, while the claims are definitions of the actualscope thereof.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the invention with the Wheels removed. Fig. 2 is a transverse section substantially on the line 2 2 of Fig. 1. Fig. 3 is a fragmentary plan view showing part of the frame and of the gearing thereon. Fig. 4 is an enlarged partlysectional elevation showing the rack and pinion for raising and lowering the bed. Fig. 5 is apartly-sectional plan of the same parts; and Fig. 6 is an enlarged sectional plan view substantially on the line 6 6 in Fig. 1, illustrating the manner of mounting the brackets which carry the dumping-body.

'7 represents the front axle, and Sthe rear axle. The bed of the wagon is formed of two parallel longitudinally-extending I-beams 9,

which are held spaced apart parallel with each other and rigidly fastened together at and near their front ends by transverse timbers 10. (Illustrated by dotted lines in Fig. 1.) The beams 9 constitute the side beams of the bed, and they extend rearward to a point just beyond the axle 8. These beams 9 are fastened to the axle 8 by means of brackets 11, which are secured rigidly to the under sides of the beams and attached to the axle in any suitable manner. By this arrangement. the parts 8, 11, and 9 are held rigidly together. The front axle 7 is connected with the bed of the wagon by mechanism of any desired sort to permit the proper movement of the axle in turning the Wagon, all of which will be understood.

Fastened rigidly toand extending between the brackets 11, just above the axle 8 and parallel therewith, is a shaft 12, on which is fitted to turn freely a pipe let. (See Fig. 6.) To this pipe 14 are rigidly fastened brackets 15, which are located between the brackets 11 and the beams 9 and to which the under side of the Wagon-body 16 is firmly secured. this arrangement the body 16 is mounted to rock around the axis of the shaft 12, so as to occupy a horizontal position for carrying a load or to occupy an inclined position for dumping it. The purpose of providing the shaft 12 and the pipe 141 to turn thereon is to assist in strengthening the connection between theparts 11 and the members attached thereto and also to provide a very strong means of rockably mounting the body.

The rear ends of the beams 9 are rounded downward, as shown in Fig. 1, and the bottom of the body is provided with wear-plates 17, which bear, respectively, on the rounded rear ends of the beams 9. These rounded portions of the beams are formed with an arc-shaped curve, the center of which are is coincident with the axis of the shaft 12. Consequently when the body 16 is rocking it bears at all times upon the convex portions of the beams 9, which serve to assist in supporting the body. It will therefore be seen that the weight of the body is evenly distributed throughout the various parts of the wagon, and this enables me to carry great loads upon the body withoutdanger of breaking the wagon and also without requiring great force to move the body from one position to another. When the body is at rest, the wear-plates l7 bear flat upon the beams 9, which in this case bear the major portion of the load of the vehicle.

For raising and lowering the body I provide two racks 18, which arepivotally mounted on the under side of the wagon-body and which are in mesh with pinions 19, fastened on a shaft 20. The racks 18 are held properly engaged with the pinions by means of outer ends ansantifiriction-roller. 22,,bearing against theft-front @edge of the racks,1;th-'ereby holding the racks engaged with the pinions and atthe same time allowing free movement of the racks between the links 21. lhe shaft is mounted to turn freely inboxes 23,.fastened to the under sides of-the" beams 9. (See Fig. 2.) The left-hand end of the shaft 20 projects beyond the corresponding beam 9and is mounted in a bracket 24, attached to the outer side of the beam. This end of the shaft-2O carries aspirin-gear;=2 5,nmeshing with a pinion 26, which is fast on a short shaft 27, mounted in the bracket 24, andin a'b'0X28, attached to the outer side of the I-beam' 9.
